We are trying to specify the voltage value at each node in a mesh. Using sv_init lets us easily specify a voltage value for all of the cells in a region.

Is it possible to specify the voltage value of each cell (or node) using sv_init? Or would we have to create individual regions in the mesh and use sv_init for each region? Or is there another way?

The voltage just as an initial condition for the ionic model or as a boundary condition for the whole time?

The voltage as an initial condition.

Our workflow for context:
We are trying to initialize every node of an ellipsoid mesh to a specified starting voltage. We want to be able to specify the value on a per node basis.

The .nodal() markup with an adjustment on the state variable should be the best way:

Similar to adjusting for example maximum conductances in the ionic model: https://opencarp.org/documentation/examples/02_ep_tissue/05e_smooth_gradient_heterogeneities
